lThis invention relates to an industrial truck capable of engaging and lifting a load, trans orting it from on'elocation to another and discharging it at the latter position.

One object of the invention is to provide an improved truck of this character having an elevating member capable of moving upwardly and downwardly and also laterally relative to the longitudinal axis of the truek,

whereby the picking up of a load and its dis- 'charge is greatly facilitated.

Another object of the invention is to p rovide an improved industrial truck in which the elevating member is movable along an inclined plane, whereby the load can be dis'- charged in close engagement with an upstanding wall or readily removed therefrom.

Another object of the invention is to provide an improved industrial truck in which the elevating member is movable along an inclined plane and also laterally relative to the longitudinal axis of the truck, whereby loads may be readily discharged in close engagement with or removed from up-standing walls in front of orvat one side of .the truck.

'A further object of the invention is to provide an improved truck having an elevating member so mounted that loads can be en- Y-gaged and picked up with great facility and 4parent to those skilled in the art'to which my invention relates from the following description taken in connection` with the ac`I companying drawings, wherein Fig; l is a side elevation of al truck embodying my invention.

In the drawings, l indicates a frame mounted on a plurality of wheels, preferably two pairs of wheels 2, 3, either pair of which may be driven. In the preferred form of construction, the frame l is constructed to form a main section la and a relatively low section lb, in which arrangement the wheels 3 are plan view of parts shown in relatively'small so that the,v driving means,

which areV mounted in a suitable housing 4, are operatively connected to thewheels 2. The main frame section la includes longitudinal sills lc from which depend drop `plates 5. The low frame section 1b comprises a pair of members-5a (see Fig. 6)*connected at their inner ends to the drop plates 5 and bent inwardly at their outer ends so as to lie between the wheels 3 and connected by an angle bar 6. The horizontal flange 6a of the bar 6 serves as a track or guide, as will hereafter appear. The housing 4 is connected with a cradle 7 which supports a motor 8, the motor being connected vthrough a propeller shaft with the driving means within the housing 4 to drive the wheels 2. The cradle Zand hous-` ing 4 are operatively connected to the frame l by a suspension mechanism, one element thereof being shown at 9 but no claim is made herein to suchv mechanism since the same forms the subject-matter ofV an application filed by John H. Hertner, of Cleveland, Ohio, and myself jointly (see Letters Patent No.` 1,628,145).

indicates a source of power supply, preferably comprising electric batteries, enclosed in a casing 11 and support-ed on the frame section 1a and supplying current to the motor 8.

12 indicates a pair of uprights supporting below the framer section 1a a pair of brackets 13 and above the frame section a. dash 14 and aV controller 15. 16 indicates a platform on which the operative stands to operate the truck and its load engaging and carrying member, indicated as an entirety at 17. The platform 16 is mounted on a shaft 16a, suitably carried by the brackets 1.3. The controller 15 is operated in the usual manner through an arm 15a and a link 15b connected to a hand leverl 18swingably mounted on the dash 14:. 19 indicates a brake mechanism lcomprising a wheel'fixed to the extended end of the propeller shaft and engaged by suitable braking elements 19a. The elements 19a are operated to engageand disengage the wheel by devices 196', to which a linkage 20 is operatively connected. The linkage 20 is con nected with a foot pedal 21 which is asso- `^ciatedwith the platform 16., 22 indicates a spring connected to the linkage 20 and no-rmally tending to holdl the braking elements 19a in engagement with the brake wheel, and thefoot pedal in the position shown in Fig. 1,

Vso that operation of the latter downwardly will release the brake and permit driving of 5@comprising a handle'or tiller.

fthe frame sectionl by angles 27.

wheels' 2,Y 3, arel connected for simultaneous 3 are mounted onknuckles 26at the opposite f lendvof'an axle 27, fixed-'to the underside of The steering by devices 28operated through an arm 29 on the lower end of a steeringcolumn 30 having an operating device 31, preferably The load engaging and carrying member 17 is-mounted to move upwardly and downwardly and alsolaterally relatively to the longitudinal axis of the .frame 1 preferably toeitherside of such axis, as shown in dotted lines in 2. Several advantages follow from this construction and arrangement, for

example, if they truck has been driven up to the position to engage a load and the operative Vsees that the elevating member is not in proper position or inline with the center of the load, he may shift the member laterally without backing o'if thetruck and making another attempt to drive thetruck into proper v position. y This saine operation may be effected where the load is to be discharged in a certain position. This construction is also advantageous where loads of substantially uniform size are to be stacked, one on another since it enables them to be evenly stacked without manipulating the truck to secure this result or manually shifting each load as it is discharged. This construction also permits the loads to be discharged in close'engagement with lateral upstanding walls. In trucks of this general type, the truck frame is relatively wide at one end to secure stability and to provide ample room for batteries and the traction motor, whereas the load carrying member is relatively narrow so that it maybe projected below a skid and then raised. This arrangement prevents the discharge of a load against, or the picking up ofl a load adjacent an upstanding wall except by driving thetruck in an endwise direction, but

in my present construction, the truckfmay-be u driven in a direction parallel to a-wall and u the "load discharged in close engagement therewith i load carrying member may be moved laterally toward the wall and hence discharge the load adjacent thereto or pick the loadV up from such position.

My invention may be used to advantage in loading and unloading freight cars and other walled areas, particularly where dunnage is used between the loads and also between the loads and the walls. To secure themost ad'- vantageous results, the load engaging and carrying member, instead of ,moving'verticale wardly toward the iiooring and also outward` ly toward thedunnage with the result that the lattery is engaged andli'eld'relatively sta-V tionary by the load. By mounting the load en aOin and Carr iin member to movelaterally and also outwardly inthe longitudinal plane of the framel, it may beoperatedto or picked up therefroinsince the advantageunder these particular conditions.;

By proper positioning of the truck, the'loads may be discharged in tight :engagement with the dunnage to insuremaximum loading of the freightcar or other space and to avoid movement of the loads onerelative to the other while the car in transit. By reason of this mounting, the unloading of a freight car may be readily effected, since in raising the load engaging member or in moving it laterally inwardly, the load is bodily moved away from the other loads or the adjacent wall. y

` Of the load engaging. and carrying member 17, 32 indicatesa pair of spaced plates connected together by a plurality of devices, for

a yoke or brace 32d. The plates 32 are shaped example, the rods 3205v and 32h, a plate 320 and horizontal portions may normally extend outwardly in a horizontal direction, whereby, upon the operation of the truck, they .may be projected below a load to engage and lift it or be removed from below a load when and after the latter is lowered into its discharging position. The L-shaped members 17 may be adjusted along the support independentlyof each other and fixed in their adjusted position in any desired manner. For reasons already set forth, the member17 is raised and lowered in an inclined plane, preferably approximating an angle of degrees. By preference, the guides, indicated at 33, are carried by the inner walls of the plates 32 and engage pairs of rolls 34, 35, mounted on a base member, indicated as an entirety at 36,

adapted to be moved preferably by a suitable means, indicated as an entirety at 37 laterallyy in either direction relative to the longitudinal axis of the frame 1, to the posie tions shown in dotted lines in Fig. 2. The

guides 33 may comprise plates secured to the plates 32 and having their upper and lower side edges disposed parallel to each other, the lower edges engaging the rolls 34, 35, and

their upper edges engaging rolls 38, mounted on stud shafts 39 extending laterally from the uprights 41 forming parts of the base member 36. y These latter rolls maintain the load engaging and carrying member 17 in upright rposition and prevent it from tipping while moving on therolls 34, 35, and hence co-act with the latter to guide the member 17 in the desired direction. I

The base member 36, in the form of construction herein illustrated, comprises the following: 40 indicates side plates having upright portions 41 (already referred to) connected by a` rod 32e having a .spacing sleeve 32ev thereon between the plates to which the plates are secured by nuts 32,`and depending portions 42. The depending portions are connected by transverse plates 43v disposed against the opposite side edges thereof and secured to said portions in any desired manner. 44 indicates anglesr extending along inner walls of the plates 40. The angles 44 are secured to a transverse angle 45 and angles 46. The angles 46 support a. base plate 47 and the angles 45 and 46 support pair of transverse plates 48, 49, the purpose of which will later appear. The plates 43 are formed with pairs'of aligned openings for shafts 50 on which are loosely mounted rollers 51 engaging lthe flange 6a or a wear plate 6a', thereon; whereas the plates 48, 49, support a pair of shafts 52, on which rollers 53 are loosely mounted. The rollers 53 roll .on a track or guide 54 extending transversely along and suitably supported by the rear wall wardly due tothe weight of a load on the member 17. y

.56 indicates as an entirety a means for guiding the base member 36 inits traversing'r movements. Of these means, 57 indicates a transverse plate preferably riveted to the under side of the angle constituting the trackv 54 and extending outwardlyv therefrom. Along its free edge, the plate 57 carries aseries Vof up-standing stud shafts 58 disposed in a plane at right angles to the longitudinal axis ofthe frame 1. Rollers 59y are loosely mounted on the shafts 58 and engage withthe inner opposing faces of the plates 48, 49, or wear strips thereon, and co-act therewith to insure the lateral travel or traversing y,movements of-the base member 36 and-parts carried thereby transversely and to maintain the supporting rollers 51 and 53 in rollingA relation with their respective tracks 6a,`54.

112 indicates as an entirety a power mechafusi nism for raising and lowering the elevating member y17.y Of this mechanism, 113 indicates standards mounted on the base '47 andv provided with hollow bosses 1132 and inward- Y The chains mayhave their inner ends fixed to the sprockets-see-Fig. 3; vThe chains are guidedaround sprockets 1195, loosely mounted on ashaft 120, supported by therplates 41. The' outer portions of the chains run'around y sprockets 120e, vloosely mounted on a shaft 1206. rIlhe shaft 120?) is suitably-supported' at its opposite ends in the plates 32 and extended rwalls 33a of the guide 33, the vfree ends of the chains 119@ being connected to bars 59 forming parts of a clamping mechanism 60, to which reference will later be made. By means of these connections, the chains v119e operate to raise the load engaging and 122 indicateswebs or walls on the outer ends 125 in turn mesh with internal Vring gears" 126 provided in the innerwalls of the sectionsl of the casing sections 115 and having axial openings 122a forming bearings for a driven shaft 123 which projects at vits ends through the bearings and carries outwardly thereof pinions 124. The outer ends of the shaft are reduced and rotatably fit openings formed in the inner ends of the shafts 118, the pinions 124 being preferably formed integrally with `the shaft and the center portion of the latter beingenlarged to form shoulders that engage the bearing .walls to prevent endwise movement of the shaft. The pinions 124 mesh with gears 125 rotatably mounted on stud shafts 125e carried by the disks and the gears V114,:whereby a planetary gear reduction is provided between the shaft 123 and each'disk 121. 126e indicates Va gear fixed to the shaft 123 substantially centrally thereof and in mesh-.with a pinion 127 fixed to a shaft 128 v which is mounted at its ends in suitable bear-V ings K'128a. The bearings j 128e are mounted in awell known manner in hollow bosses 115e provided onthefupperportions of the casing members l115. v129 indicates a gear fixed to the shaft 128 and meshing with a pinion 130 xed to a shaft 131n'1ounted in'a supplemental'or cover section 132. 133 indicates a gear fixed to the shaft 131 and meshing with a pinion-` 134 fixed to a shaft 134e, which is connected (preferably detachably) at one end to the shaft of amotor 135 arranged to be supplied '5 with current from the batteries 10. The adjacent end of the motor casing removably fits the walls of an opening 132e formedin the sidewall of the cover section 132, being held rigidly in such position by a bracket or cradle V'extending laterally from the cover section 132 and a strapL or other clamping device v136 en-l,

' gaging the motor casing and bracket. The other end of the shaft 134a is mounted in suit- VesY able bearings in an opening in theV adjacent lside wall of the cover section and extends therethrough' and carries on its outer or free end a disk 137, which constitutes'one element of a brake 138. The other element of the brake consists of a disk 139 held against rotation by but slidable on aseries of bolts 139e which secure vthe cover 140 to a plate 141 having a boss fitting the bearing opening and secured therein by the shoulder of a sleeve when-the latter is started the coil is energized and the brake released.

The limit switch mechanism 145 comprises i a casina 146 secured to an 11p-standing bracket 146e. The bracket is secured to one' side of the casing 112 by the bolts or Lcap screws146a (see Fig. 9). The casing 146 encloses a pair of switches either of which is opened toy break the motor circuit by a devicey within the casing and operated by the rock shaft 147 148 indicates an arm fixed to the rock.` shaft 147. The limit `switch mechanism 145 for the motor 135 is operatively connected with the load engaging and carryingmember `17 and with one of the driven sprockets119. By means of the conf nections A'between the switch mechanism and the adjacent sprocket 119.1the switchmeclianism is operated to stop the motor 135 when the member 17 reaches its limit of movement downwardly; whereas, by means of the connections between the switch mechanism` and theload engaging and carrying member 17, the lswitch mechanismV is operated to stop the motor when the member reaches its limit of movement upwardly.. These separate con- A nections arerequiredby reason of the fact that the; 'hoist chains' 119e' are operatively connected to 'the clamping means, already referred to,` and it desirable to stop the motor when the load'engaging and carrying member 17 hasmoved upwardly' a predeterminedV distance,` "but ifv in,` the downward movement ofthe member 17 the connections with the'switch mechanism'were arranged toA operate the 'latter and an obstruction p should prevent the complete downward movement of the member 17,-th en these connections would'b'e ineffective to ystop the mo-i tor. By lproviding' separate connections controlled by one of the sprockets 119, or other j driven element, I prevent the paying out ofl the hoist chains 119e beyond a predetermined amount.` These operating connections may consist of the J following: 1480: indicates a link connected atroneend to the arm 148 and at itsopposite endto an arm 1486 fixed toa shaft148c. "149 'indicates an'arm fixedl to t-he shaft 1480. The outer end of the arinv 149jis bifurcate'd and formed with aligned openings toV receive a rotatable plug 149e which is slotted to slidably receive abar 150.

he bar 150 extends downwardly through and slidablyfit-s aligned openings formed in the adjacent casing section 1130. The inner edge orfa'ce of the bar' 150 is provided 'with' a rack which? meshes with a pinion 151 fixedV to the` hub of the' adjacent sprocket 119, whereby the pinion 151 is rotated and the bar movedV endwise upwardly or downwardly when thepower transmitting mechanismY is operated.` The upper portion'of the bar 150 is provided with an adjustable tappetf152 which serves to engage the arm 149, when Y moved downwardly and thus effect an opening or'bre'aking of the motor circuit/followfing the rotating of the sprockets 119 to pay out the'chains 1190i and lowering of the lift member 17 to its lowermost position. 149 indicates a separate arm fixed to the'shaft 1480, `,its outer end being bifurcated and formed with alignedopenings to receive `,a rotatable plug 149e. The plug 1495i is slotted to slidably receive a rod 150 pivotally connected at its lower free end to the adjacent side plate 32 (see F ig. 9),whereby the rod is moved endwise by the member 17. Near its lower end, the rod 150 carriesv an adjustable tappet 152@` which, in the upward movement of the member 17 a predetermined distance, is adapted to-engage thearm 149 and through it and the connections referred to with the switch mechanism, to lopen the motor circuit and thus stop the motor 135. The means 37 for moving or traversing the base member 36 and parts carried thereby laterally or transversely preferably comprise one or more racks and a pinion engaging each rack. In thepresent illustrated form of construction I provide two spaced racks'` 61 on the lower side of the base member 36 and mount the pinions 61a on the frame section 11). By 4preference .the pinions are power driven by a motor 62, receiving current from the batteries 10. The motor 62 is associated with a casing 63 Vhaving at one end suitable gear reduction driven by the shaft of the motor and driving a gear 64 (see Fig. 11) and having at its other end a gear train for driving the pinions 61a. The shaftfor the motor 62 is extended and providedgwith a member with which a magnetically controlled brake element engages. The member 4and elements and the control devices for the latter are mounted in a housing 63 and are preferably similar to like elements andparts shown in Fig. 7. The casing 63 is provided with feet or standards 63a. resting on cross pieces 63?) carried by the frame section 1b (see Fig. 3). The gear64 is keyed to a shaft 65 having apinion 66. The pinion 66 drives a gear 67 mounted in the casing walls and having fixed to it a pinion 68 in mesh with a gear 69. The gear 69 is fixed to a shaft 70 whichextends beyond the walls vof the casing and carries the pinion 61a.v This arrangement provides for the positive driving of the pinions 61a at the same speed.

71 indicatesa casing containing pairs of contacts, one of which is opened to break the circuit to the motor 62 when the base member 36 reaches a predetermined position in moving laterally ineither direction.. The casing 71 is mounted on an angle 72 carried by one of the drop plates 5. 73 indicates a rock shaft carrying within the casing devices to control the openingtof either pair of contacts.v On its outer end,.the 'shaft 73 is provided with an arm 74`to which is pivoted one end of a link 75. The opposite end of the link 7 5 is pivotally connected to an arm 76 fixed to a shaft 7 7. The opposite ends of the shaft 77 are suitably supported by brackets 77a preferablyA secured to the covers or end walls of the casing 63 and extending to one side thereof. 7 8 indicates a separate arm carried by the shaft 77 `and carrying a link 7 9 pivotally connected to a cross head 80. The j cross head80 isformed with an opening through which slides a rod 8l supported at its taln 1t on the load engaging and carryingA member 17 while the load is in transit and While it is being moved upwardly and downwardly. As shown, the raising and lowering means 112 is interconnected with the clamping means 60 so that thelatter is first operated to clamp the load in the operation of picking it up, and in discharging a load, the

engagement of the load with its support in paying out the chains serves to effect automatic release of the clamping means from the load. The bars 59 are mounted at their inner ends on stud shafts 83 mounted on vthe inner walls of the plates 32 and carry at their outer ends a clamping member 8,4, such ends being preferably pivoted to up-standing ears 84a. The bars 59 and ears 84a are formed with seriesv of openings to permit of adjustment of the member vertically relative to the engaging and lift elements 17 or horizontally relative the'vertical portions thereof.

The clamping member 84 is normally maintained inV an inoperative position, that is, .in an elevated position, against a stop 84, to permit the lelements 17 to be projected below the load with the clamping member abovey it. The clamping member 84e is preferably held in `elevated position by one or more sets of devices 85, each set comprising the following: 85a indicates a yoke member pivoted at one end to the adjacent bar 59. The yoke member straddles a compression spring 852) and its opposite end is bent to form a seat 85e for one end of the spring 85?). 86 indicates a rod suitably fixed to and depending from a cross member86a rotatably supported at its opposite ends vin the plates 32 near their upper ends. The rod 86 extends through an opening formed in the seat 85o (being guided by the walls of the opening) and carries at its free end a collar 86?) which forms a seat for the opposite ends of the spring 85?). The springs V8512 are of a size and strength to act through the yoke members 85a to normally hold the clamping member '84 inits elevated positionand are preferably strong enough to overcome the Weight ofthe load engaging and carrying member 17 so that the clamping member 84 will remain in elevated position when the member 17 is being operated without a load, but when this member engages a load, the increase in weight resulting therefrom will cause the pull on the chains 119a Vto operate the clamping member 84 as lifting of the'load takes place, and thus clamp the load on the member 17. s

' 84m indicates a stop to limit movement of the arms 59 downwardly and thus enable vthe raising and lowering means to be effective where the load is not large enough to be clamped bythe member 84. f'

` From the foregoing description it will be seen that I have provided an elevating member capable of moving upwardly and downwardly and that such member is mounted on a transversely movable carriage, makingv it possible to move such member or a load thereon upwardly and downwardly and also laterally, whereby such member may be readily moved or adjusted into operative relationship to a load or the support or devices on which a load is to be discharged'. This form of construction permits the load engaging member to be moved laterally when in its lowermost position (see dotted lines on the lower side of Fig. 2) or when in its raised position (see dotted lines on the upper side of Fig. 2) or when in any intermediate'position. Y

It will also be seen that the construction is relatively simple and easily controlled. In the illustrated construction, thedrivers station is at the outer end of the frame section 1a and adjacent thereto I provide a controller 87 having a handle 87a foro'perating the motor 135 and a handle 88 connected by a shaft 90 to a cont-roller'91 for operating the motor 62. By operating both controllers 87 and 91, the elevating member 17 may be operated upwardly or downwardly and laterally simultaneously. i a
